On April 1, 2010: I was looking for down with over 700 FP, gusset, at least 50% silk cover fabric and a good price. There was no king size for one I liked most, so I picked this one. It arrived promptly and well packaged. I like the cover fabric very much: it’s true 51% silk. Very soft and no feather flew after I shook it a few times. It’s 85% down not 100%.
